Main Briefintroduction of Truck Crane QY25E431:

This type of truck crane, one of the classic products in the same trade, has earned a good reputation from the customers.

The truck crane adopts self–made special-purpose chassis with 6×4 drive. The ergonomic streamline semi-mounted driver’s cab with double wing door, which has obtained a national patent, makes it convenient for rear rider to get on/off cab.

The crane adopts WEICHAI Steyr engine which is specially developed for those cranes that often travel at low speed. This kind of engine not only can produce large output torque when it starts and increase the traveling speed quickly, but also has excellent starting performance and good gradeability.

The crane is equipped with 8-speed gearbox which changes gear smoothly and is of simple structure and makes maintenance convenient.

Advantage

The crane is fitted with a 33.3m long hexagon-section boom which is made of high-strength steel, so the boom has strong resistance to bending and torsion. The distinctively-designed circular arc sliding block (having obtained a national patent) makes the stress distributed more evenly, the load carrying capacity stronger, and the adjustment easier. The local rigidity in boom supporting point is good, which has improved the lifting capacity on boom with same thickness and achieved the goal of greater lifting capacity on lighter boom.

The unique manual full proportional control incorporates the advantages of traditional lever control and electric-hydraulic pilot control. It not only reserves the merits of safety & reliability of original control structure and low maintenance cost, but also realizes that the working speed of actuating mechanism is only proportional to the opening degree of control valves rather than affected by the load. Furthermore, it has improved the speed-regulation performance.

The slewing mechanism has the functions of protecting the crane automatically when the crane is overloaded, reducing the impacts, and activating hydraulic brake when the hydraulic control valve is in neutral position as well as free swing. In addition, it can automatically make boom, wire rope and lifted load slew simultaneously, and minimize the sway of boom and load while the crane starts or stops quickly, and accelerates or decelerates slewing.

Hydralic System

We have made constant improvements on our products, for instance, adding radiator for hydraulic system and mounting hydraulic oil tank of large capacity on the slewing table. Therefore, the radiating performance of hydraulic system is improved and the continuous working hours are 2~3 times of that of the same trade’s products.

The crane is fitted with outrigger lamps which can facilitate operation at night.

The crane is equipped with high-quality load moment limiter which has such advantages as great precision and complete information shown on the display. In this way, the safe lifting operation can be guaranteed.

ZOOMLION CRANE

Q:What is the principle of the arm boom of the boom-type truck crane?: There are two ways in which the boom is extended and retracted; sequential telescopic and synchronous telescopic

Q:Is the crane (a truck crane) a truck?: Article 2 of the Regulations of the People's Republic of China on Road Transport stipulates that "the road transport operations referred to in the preceding paragraph shall include road passenger transport operations (hereinafter referred to as passenger transport operations) and roads

Q:What is the difference between the main arm and the basic arm of a truck crane?: The basic arm is to distinguish it from the second (three, four, five) arm, which is part of the main arm.

Q:Why the car crane rotation angle can not be more than 45 degrees: About the rotation angle is too large, will make the center of gravity out of the scope of support, resulting in truck crane rollover.

Q:What are the specifications and standards for truck cranes and tire cranes?: Safety technical conditions for motor vehicle operation GB 7258

Q:How is the length of the main hoist's main winch and sub-winch wire rope calculated?: When the lifting angle of the boom is maximum, the wire rope override (generally not the full magnification of the main hook) is specified according to the specifications of the crane, and the length of the main rope is the length of the main rope.

Q:What about the Reza car cranes?: Lei Sa has a high quality service network, convenient service, quick response.

Q:What are the parameters of the QY35 truck crane?: Rated power kW / (r / min) 235/2200 Engine rated torque Nm / (r / min) 1250/1400 Travel parameters Maximum travel speed km / h 75 Minimum turning diameter m 19.5 Minimum ground clearance mm 260 Proximity angle 17

Q:What is a wheeled crane: According to the crane design manual to divide the words: tire cranes, truck cranes, crawler cranes are tied, belong to the fixed rotary crane!

Q:What is the development trend of truck cranes in China?: Larger tonnage of new products to meet the needs of the market. The only way to get nutrients and vitality from the market to survive, survive in development, grow in development
